Seems like people are doing alot of moving. Really you can spread out near the big bone structures south of him, and just move your DPS one at a time as he tosses goo at them.

Only time you really need to start moving is when hes pursuing, if you BOP the person getting persuit you can pretty much just ignore it and keep dpsing. He shouldnt get through more then one pursuit if your dps is doing good.

After pursuit I dps a bit more and then move back to grab the crew with /follow. He should be about to start casting his arcane mine stuff and then I just run around in a circle with the toons on follow. Great time to drop fire elementals and let them whoop up on his ass btw.
